Wouldn't be reliable anyway: there is nothing to prevent
udhcpd to race with hostapd. It will die whenever interface is going down.

I suggest stopping playing russian roulette and putting all your daemons
into a service supervision system of your choosing. I personally use
a system described here:

https://git.busybox.net/busybox/tree/examples/var_service/README

See "Networking examples" section, and other files beside README
in this directory.

However, you can use any other system you like.
